Abstract
The utility model discloses a kind of brake apparatus hydraulic system, including checking cylinder, releasing brake circuit, auxiliary braking oil circuit, foot pedal hydraulic valve draining oil circuit, hydraulic control one-way valve, foot pedal hydraulic valve, check valve, volume adjustable hydraulic pump, motor.During normal operation, the opening speed that the hydraulic system can trample foot pedal hydraulic valve speed control brake shoe by control realizes the regulation of the elevator speed of service, under parking and accident conditions, disk spring can apply brake force, auxiliary braking oil circuit and hydraulic control one-way valve can realize auxiliary braking simultaneously, the handling of system is improved, improves the reliability of brake apparatus braking and the security of elevator operation.
Description
Technical field
A kind of brake apparatus hydraulic system is the utility model is related to, suitable for controlling brake for elevator device.
Background technology
Elevator is the plant equipment transported by changing potential energy, is primarily adapted for use in powdery, graininess and fritter thing
The continuous and perpendicular lifting of material, such as mine hoist, hoist engine.Hoist braking system is the important component of elevator,
It is that brake force is applied to mine hoist in a manner of mechanical friction, participates in speed governing and realize the device of parking, the control of brake apparatus
System uses hydraulic system, therefore the reliability of brake apparatus hydraulic work system directly influences the work safety of elevator,
And the element such as magnetic valve, pressure regulator valve in the hydraulic system of traditional braking device easily breaks down, brake for elevator can be caused
Failure, trigger security incident.
The content of the invention
The purpose of this utility model is deficiencies of the prior art to be solved, there is provided a kind of simple system, is easy to
Operation, safe and reliable brake apparatus hydraulic system.
Technical scheme is used by the utility model：
A kind of brake apparatus hydraulic system, it is characterized in that：Including checking cylinder, release brake circuit, auxiliary braking oil
Road, foot pedal hydraulic valve draining oil circuit, hydraulic control one-way valve, foot pedal hydraulic valve, check valve, volume adjustable hydraulic pump, motor.The checking cylinder
Disk spring is provided with rodless cavity.
The beneficial effects of the utility model are：
Auxiliary braking oil circuit and hydraulic control one-way valve are provided with system, under dead ship condition, can be achieved to utilize system pressure
Aid in disk spring to apply the reliable braking hoister of brake force, disk spring is set in checking cylinder rodless cavity, in the state of accident
Also braking hoister that can be safe in time, improves the reliability of brake apparatus braking and the security of elevator operation.
The opening speed of brake shoe can be controlled by trampling foot pedal hydraulic valve speed by control, and then adjust the operation of elevator
Speed, improve the handling of system.
The setting of foot pedal hydraulic valve draining oil circuit makes the hydraulic oil of foot pedal hydraulic valve internal leakage discharge in time in system, prevents
Because the hydraulic oil accumulation of leakage causes the foot pedal hydraulic valve to malfunction.
Brief description of the drawings
Fig. 1 is systematic schematic diagram of the present utility model.
Fig. 2 is this practical checking cylinder schematic diagram.
In figure：1- lifting drums, 2- lifting drum braked wheels, 3- checking cylinders, 301- checking cylinder rod chambers, 302-
Checking cylinder rodless cavity, 303- disk springs, 4- releasing brake circuits, 5- auxiliary braking oil circuits, 6- foot pedal hydraulic valve draining oil circuits,
7- hydraulic control one-way valves, 8- foot pedal hydraulic valves, 9- check valves, 10- volume adjustable hydraulic pumps, 11- motors.
Embodiment
As illustrated, a kind of small lift brake apparatus, including checking cylinder 3, releasing brake circuit 4, auxiliary braking oil
Road 5, foot pedal hydraulic valve draining oil circuit 6, hydraulic control one-way valve 7, foot pedal hydraulic valve 8, check valve 9, volume adjustable hydraulic pump 10, motor 11.
Operation principle of the present utility model is accidental conditions：Foot pedal hydraulic valve 8 is trampled, foot pedal hydraulic valve 8 is in right position, hydraulic pressure
Oil enters the promotion brake shoe of checking cylinder rod chamber 301 via brake circuit 4 is released（It is not shown）Open, lifting drum braked wheel 2
Brake release, lifting drum 1 can carry out enhancing action, and brake shoe can be controlled by trampling the speed of foot pedal hydraulic valve 8 by control（Figure
Do not show）Opening speed, and then adjust lifting drum 1 the speed of service, stop operating mode：Foot pedal hydraulic valve 8 is not trampled, pin
Step on hydraulic valve 8 and be in left position, the disk spring 303 in checking cylinder rodless cavity 302 applies brake force and promotes brake shoe（It is not shown）Close
Braking hoister reel braked wheel 2 is closed, while hydraulic control one-way valve 7 pins the hydraulic oil in auxiliary braking oil circuit 5, makes auxiliary braking
Oil circuit 5 forms the loop of a closing, aids in the reliable braking hoister reel braked wheel 2 of disk spring 303, accident conditions：Liquid
When hydraulic oil in pressure system loses pressure, the disk spring 303 in checking cylinder rodless cavity 302 applies brake force and promotes lock
Watt（It is not shown）Close brake hard lifting drum braked wheel 2.
